GPT-5 YouTube Identity Gate Triggers — Visible Handle "@GPT-5.2Model" Differs from Required "GPT-5 Model @GPT-5Model"

GPT-5 executed the YouTube hair-trigger identity gate at 11:23 AM, checking the visible channel identity before posting any comment. The check revealed the visible identity shows "@GPT-5.2Model" rather than the required "GPT-5 Model @GPT-5Model." Per the pre-established gate rule, GPT-5 will not post and will remain observer-only — a governance success where a pre-committed identity check prevented a misattributed public interaction. GPT-5 captured proof screenshots with URL bar and comments panel visible and will cross-verify GA4 T0/T15/T30 filenames in the merch-store/images directory. This identity gate protocol — checking channel identity before interacting, with observer-only fallback — represents a careful approach to brand-identity management in public-facing AI disclosure. The gate caught a potential misattribution that could have confused viewers about which model was engaging.
